For ease of description, the following describes some terms involved in the embodiments of this disclosure:
Packet data convergence protocol (PDCP for short) duplication (that is, PDCP Duplication) transmission:
The network side device can configure whether the PDCP layer of a radio bearer (RB) of the terminal device (which may be also referred to as user equipment, UE for short) transmits, after data of a PDCP entity is duplicated, the duplicated data through at least two different paths, such as two different radio link control (RLC) entities, for transmission. Different RLC entities correspond to different logical channels.
It should be noted that the PDCP data duplication function can indicate whether it is to be started (that is, activated) or stopped (that is, deactivated) through media access control layer control signaling (MAC CE). Optionally, when configuring the PDCP data duplication function of the RB, the network-side device can configure whether the PDCP data duplication function is enabled immediately upon configuration, that is, no MAC CE signaling is required for additional activation.
Bearer types of the PDCP data duplication function:
In a future mobile communications system (for example, the fifth generation (5G for short) system), due to the dual connectivity (DC) architecture which includes two cell groups, namely a master cell group (MCG) and a secondary cell group (SCG), the PDCP data duplication function includes two bearer types shown in
Duplicate bearer: One PDCP entity, at least two RLC entities (two RLC entities are used as an example in
Split bearer: A PDCP entity corresponding to the bearer is in one cell group, and at least two RLC entities (two RLC entities are used as an example in
Multiple path PDCP data duplication (that is, Multiple Leg PDCP Duplication):
As shown in
An embodiment of this disclosure provides a resource allocation method.
In this embodiment of this disclosure, the network-side device 12 can configure uplink resource allocation rule information for one or at least two paths of a bearer of the terminal device 11. The uplink resource allocation rule information may include a first uplink resource allocation rule and/or a second uplink resource allocation rule, the first uplink resource allocation rule may be an uplink resource allocation rule used when the path is in an activated state, and the second uplink resource allocation rule may be an uplink resource allocation rule used when the path is in a deactivated state.
The bearer may include but is not limited to signaling radio bearer (SRB) or data radio bearer (DRB). The path may include but is not limited to an RLC entity or a logical channel.
Optionally, when the network-side device 12 configures only one path for the bearer of the terminal device 11, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for the path; and when the network-side device 12 configures at least two paths for the bearer of the terminal device 11, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for each of the two paths.
It should be noted that the first uplink resource allocation rule configured for different paths of the at least two paths may be the same or different; and the second uplink resource allocation rule configured for different paths of the at least two paths may be the same or different.
After receiving the uplink resource allocation rule information, the terminal device 11 can perform uplink resource allocation based on the uplink resource allocation rule information. For example, when the path is in the activated state, the first uplink resource allocation rule is used to allocate an uplink resource for the path; and when the path is in the deactivated state, the second uplink resource allocation rule is used to allocate an uplink resource for the path.
In the resource allocation method according to this embodiment of this disclosure, because the first uplink resource allocation rule and the second uplink resource allocation rule are resource allocation rules respectively configured for different states of a path, resources can be allocated flexibly for the path of the bearer of the terminal device by receiving the first uplink resource allocation rule and/or the second uplink resource allocation rule configured by the network-side device for the path of the bearer of the terminal device, and using an uplink resource allocation rule corresponding to a state of the path for uplink resource allocation, thereby improving the reliability of service data transmission.
An embodiment of this disclosure provides a resource allocation method, and the method is applied to a terminal device.
Step 601. Receive uplink resource allocation rule information configured by a network-side device for a path of a bearer of the terminal device, where the uplink resource allocation rule information includes a first uplink resource allocation rule and/or a second uplink resource allocation rule, the first uplink resource allocation rule is an uplink resource allocation rule used when the path is in an activated state, and the second uplink resource allocation rule is an uplink resource allocation rule used when the path is in a deactivated state.
In this embodiment of this disclosure, the bearer may include but is not limited to an SRB or a DRB, and the path may include but is not limited to an RLC entity or a logical channel. The uplink resource may include but is not limited to an uplink grant.
There may be one or at least two paths of the bearer of the terminal device. For example, referring to
In practical applications, when the network-side device configures only one path for the bearer of the terminal device, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for the path; and when the network-side device configures at least two paths for the bearer of the terminal device, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for each of the two paths.
It should be noted that the first uplink resource allocation rule configured for different paths of the at least two paths may be the same or different; and the second uplink resource allocation rule configured for different paths of the at least two paths may be the same or different.
Step 602. Perform uplink resource allocation based on the uplink resource allocation rule information.
In this step, after receiving the uplink resource allocation rule information, the terminal device can perform uplink resource allocation based on the uplink resource allocation rule information. For example, when the path is in the activated state, the first uplink resource allocation rule corresponding to the path can be used to allocate an uplink resource for the path; and when the path is in the deactivated state, the second uplink resource allocation rule corresponding to the path can be used to allocate an uplink resource for the path.
In the resource allocation method according to this embodiment of this disclosure, because the first uplink resource allocation rule and the second uplink resource allocation rule are resource allocation rules respectively configured for different states of a path, resources can be allocated flexibly for the path of the bearer of the terminal device by receiving the first uplink resource allocation rule and/or the second uplink resource allocation rule configured by the network-side device for the path of the bearer of the terminal device, and using an uplink resource allocation rule corresponding to a state of the path for uplink resource allocation, thereby improving the reliability of service data transmission.
Optionally, the bearer includes at least two paths.
The foregoing step 602 of performing uplink resource allocation based on the uplink resource allocation rule information includes:
allocating, by a media access control MAC entity of the terminal device based on uplink resource allocation rule information corresponding to a target path, an uplink resource for the target path, where
the target path is a path of the at least two paths which corresponds to the MAC entity.
In practical applications, the path of the bearer of the terminal device can correspond to the same MAC entity. As shown in
In this embodiment of this disclosure, the MAC entity of the terminal device can allocate resources only for its corresponding path in the process of performing uplink resource allocation. For example, the MCG MAC entity allocates uplink resources for its corresponding four RLC entities, and the SCG MAC entity allocates uplink resources for its corresponding two RLC entities.
In this embodiment of this disclosure, the MAC entity of the terminal device allocates an uplink resource for a target path based on the uplink resource allocation rule information corresponding to the target path, thereby increasing the flexibility and accuracy of uplink resource allocation.
Optionally, when the uplink resource allocation rule information includes the first uplink resource allocation rule and the second uplink resource allocation rule, the foregoing step 602 of performing uplink resource allocation based on the uplink resource allocation rule information includes:
allocating an uplink resource for the path by using the first uplink resource allocation rule when the path is in the activated state; and
allocating an uplink resource for the path by using the second uplink resource allocation rule when the path is in the deactivated state.
In this embodiment of this disclosure, if there is one path of the bearer of the terminal device, when the path is in the activated state, the first uplink resource allocation rule can be used to allocate an uplink resource for the path; and when the path is in the deactivated state, the second uplink resource allocation rule can be used to allocate an uplink resource for the path.
If there are at least two paths of the bearer of the terminal device, when a first path is in the activated state, the first uplink resource allocation rule corresponding to the first path can be used to allocate an uplink resource for the first path; and when the first path is in the deactivated state, the second uplink resource allocation rule corresponding to the first path can be used to allocate an uplink resource for the first path, where the first path is any one of the at least two paths.
In this embodiment of this disclosure, a first uplink resource allocation rule and a second uplink resource allocation rule are configured for a path of a bearer of the terminal device. When the path is in the activated state, the first uplink resource allocation rule is used to allocate an uplink resource for the path; and when the path is in the deactivated state, the second uplink resource allocation rule is used to allocate an uplink resource for the path. Because different uplink resource allocation rules are used for uplink resource allocation when the path of the bearer of the terminal device is in different states, the flexibility and accuracy of resource allocation for the path of the bearer of the terminal device can be increased, thereby improving the reliability of service data transmission.
Optionally, the first uplink resource allocation rule includes at least one of the following:
type information of a first available uplink resource; and
type information of a first unavailable uplink resource;
and/or,
the second uplink resource allocation rule includes at least one of the following:
type information of a second available uplink resource; and
type information of a second unavailable uplink resource.
In this embodiment of this disclosure, the type information of the first available uplink resource is the type information of the uplink resource available when the path is in the activated state. For example, for an uplink grant of this type, the path (for example, a logical channel) is included at the time when the UE allocates the uplink grant based on the logical channel priority (LCP). The type information of the first unavailable uplink resource is the type information of the uplink resource unavailable when the path is in the activated state. For example, for an uplink grant of this type, the path is not included at the time when the UE allocates the uplink grant based on the LCP.
The type information of the second available uplink resource is the type information of the uplink resource available when the path is in the deactivated state. For example, for an uplink grant of this type, the path (for example, a logical channel) is included at the time when the UE allocates the uplink grant based on the LCP. The type information of the second unavailable uplink resource is the type information of the uplink resource unavailable when the path is in the deactivated state. For example, for an uplink grant of this type, the path is not included at the time when the UE allocates the uplink grant based on the LCP.
In this embodiment of this disclosure, the network-side device allocates type information of the available uplink resource and/or type information of the unavailable uplink resource for different states of the path, so that the resource allocation for the path of the bearer of the terminal device is more flexible.
Optionally, the type information of the uplink resource includes at least one of the following: a sub-carrier spacing SCS corresponding to the uplink resource; a carrier corresponding to the uplink resource; a bandwidth part BWP corresponding to the uplink resource; beam information corresponding to the uplink resource; transmission node information corresponding to the uplink resource; duration of a transmission channel corresponding to the uplink resource; and grant type corresponding to the uplink resource;
and/or,

The type information of the second unavailable uplink resource may include at least one of a sub-carrier spacing corresponding to the uplink resource; a carrier corresponding to the uplink resource; a bandwidth part corresponding to the uplink resource; beam information corresponding to the uplink resource; transmission node information corresponding to the uplink resource; duration of a transmission channel corresponding to the uplink resource; grant type corresponding to the uplink resource; and information used to indicate any uplink resource unavailable.
The uplink resource may include but is not limited to an uplink grant. The value of the sub-carrier spacing corresponding to the uplink resource can be properly configured based on an actual need, for example, the SCS is equal to 15 KHz. The value of the carrier corresponding to the uplink resource can also be properly configured based on an actual need, for example, serving cell 1 or serving cell 2. The value of the bandwidth part corresponding to the uplink resource can also be properly configured based on an actual need, for example, BWP_1 or BWP_3. The duration of the transmission channel corresponding to the uplink resource can also be properly configured based on an actual need, for example, a time length of a physical uplink shared channel (Physical Uplink Sharing Channel, PUSCH) is one slot. The value of the grant type corresponding to the uplink resource can also be properly configured based on an actual need, for example, configured grant 1, configured grant 2, or autonomous uplink (AUL).
It should be noted that the value of each item included in any one of the type information of the first available uplink resource, the type information of the first unavailable uplink resource, the type information of the second available uplink resource, and the type information of the second unavailable uplink resource can be properly configured based on an actual situation.
For example, the type information of the first available uplink resource includes an SCS corresponding to the uplink resource, a carrier corresponding to the uplink resource, and a BWP corresponding to the uplink resource, where the value of the SCS corresponding to the uplink resource is 15 KHz, the carrier corresponding to the uplink resource is serving cell 1, and the BWP corresponding to the uplink resource is BWP_2. The type information of the first unavailable uplink resource includes a carrier corresponding to the uplink resource and a BWP corresponding to the uplink resource, where the carrier corresponding to the uplink resource is serving cell 2, and the BWP corresponding to the uplink resource is BWP_1. The type information of the second available uplink resource includes a carrier corresponding to the uplink resource and a grant type corresponding to the uplink resource, where the carrier corresponding to the uplink resource is serving cell 3, and the grant type corresponding to the uplink resource is configured grant 1. The type information of the second unavailable uplink resource includes a carrier corresponding to the uplink resource and a BWP corresponding to the uplink resource, where the carrier corresponding to the uplink resource is serving cell 3, and the BWP corresponding to the uplink resource is BWP_1.
It should be noted that when the type information of the first available uplink resource and/or the type information of the second available uplink resource corresponding to a specific path includes information used to indicate any uplink resource available, the path is included when the terminal device performs allocation of any type of uplink resources. When the type information of the first unavailable uplink resource and/or the type information of the second unavailable uplink resource corresponding to a specific path includes information used to indicate any uplink resource unavailable, the path is not included when the terminal device performs allocation of any type of uplink resources.
In addition, optionally, the priority of the information used to indicate any uplink resource available may be higher than the priorities of the type information of other available uplink resources (for example, an SCS corresponding to the uplink resource, a carrier corresponding to the uplink resource, a BWP corresponding to the uplink resource, and beam information corresponding to the uplink resource), and the priority of the information used to indicate any uplink resource unavailable may be higher than the priorities of the type information of other unavailable uplink resources. To be specific, when the information used to indicate any uplink resource available or the information used to indicate any uplink resource unavailable is configured, the uplink resource allocation may be preferentially performed based on the information used to indicate any uplink resource available or the information used to indicate any uplink resource unavailable.
Optionally, in the embodiments of this disclosure, when the information used to indicate any uplink resource available is configured, it is not allowed to configure the type information of other available uplink resources, and/or when the information used to indicate any uplink resource unavailable is configured, it is not allowed to configure the type information of other unavailable uplink resources, to avoid conflicts between configuration information.

An embodiment of this disclosure further provides a resource allocation method, and the method is applied to a network-side device.
Step 701. Transmit, to a terminal device, uplink resource allocation rule information configured for a path of a bearer of the terminal device, where
the uplink resource allocation rule information includes a first uplink resource allocation rule and/or a second uplink resource allocation rule, the first uplink resource allocation rule is an uplink resource allocation rule used when the path is in an activated state, and the second uplink resource allocation rule is an uplink resource allocation rule used when the path is in a deactivated state.
In this embodiment of this disclosure, the bearer may include but is not limited to an SRB or a DRB, and the path may include but is not limited to an RLC entity or a logical channel. The uplink resource may include but is not limited to an uplink grant.
There may be one or at least two paths of the bearer of the terminal device. For example, referring to
In practical applications, when the network-side device configures only one path for the bearer of the terminal device, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for the path; and when the network-side device configures at least two paths for the bearer of the terminal device, the first uplink resource allocation rule and/or the second uplink resource allocation rule can be configured for each of the two paths.
It should be noted that the first uplink resource allocation rule configured for different paths of the at least two paths may be the same or different; and the second uplink resource allocation rule configured for different paths of the at least two paths may be the same or different.
In this embodiment of this disclosure, the network-side device configures and transmits to the terminal device the first uplink resource allocation rule and/or the second uplink resource allocation rule for the path of the bearer of the terminal device. Because the first uplink resource allocation rule and the second uplink resource allocation rule are resource allocation rules respectively configured for different states of a path, the terminal device can use an uplink resource allocation rule corresponding to a state of the path for uplink resource allocation.
Optionally, the first uplink resource allocation rule includes at least one of the following:
type information of a first available uplink resource; and
type information of a first unavailable uplink resource;

type information of a second available uplink resource; and
type information of a second unavailable uplink resource.
In this embodiment of this disclosure, the type information of the first available uplink resource is the type information of the uplink resource available when the path is in the activated state. For example, for an uplink grant of this type, the path (for example, a logical channel) is included at the time when the UE allocates the uplink grant based on the LCP. The type information of the first unavailable uplink resource is the type information of the uplink resource unavailable when the path is in the activated state. For example, for an uplink grant of this type, the path is not included at the time when the UE allocates the uplink grant based on the LCP.
The type information of the second available uplink resource is the type information of the uplink resource available when the path is in the deactivated state. For example, for an uplink grant of this type, the path (for example, a logical channel) is included at the time when the UE allocates the uplink grant based on the LCP. The type information of the second unavailable uplink resource is the type information of the uplink resource unavailable when the path is in the deactivated state. For example, for an uplink grant of this type, the path is not included at the time when the UE allocates the uplink grant based on the LCP.
In this embodiment of this disclosure, the network-side device allocates type information of the available uplink resource and/or type information of the unavailable uplink resource for different states of the path, so that the resource allocation for the path of the bearer of the terminal device is more flexible.
Optionally, the type information of the uplink resource includes at least one of the following: a sub-carrier spacing SCS corresponding to the uplink resource; a carrier corresponding to the uplink resource; a bandwidth part BWP corresponding to the uplink resource; beam information corresponding to the uplink resource; transmission node information corresponding to the uplink resource; duration of a transmission channel corresponding to the uplink resource; and grant type corresponding to the uplink resource;
and/or,
the type information of the first available uplink resource and/or the type information of the second available uplink resource includes information used to indicate any uplink resource available;
and/or,
the type information of the first unavailable uplink resource and/or the type information of the second unavailable uplink resource includes information used to indicate any uplink resource unavailable.

The following describes embodiments of this disclosure with reference to
Specifically, the resource allocation method in this embodiment of this disclosure may include the following steps:
Step a1. The network-side device configures a plurality of available paths for transmission or reception for a bearer of a terminal device.
For example, as shown in
Step a2. The network-side device configures uplink resource allocation rule information for one or at least two paths of the bearer of the terminal device.
It should be noted that, reference may be made to the foregoing description for the uplink resource allocation rule information. Details are not described herein again.
It should be noted that configuration information of the step a1 and step a2 may be transmitted through one or different pieces of signaling, which is not limited in this embodiment of this disclosure.
Step a3. After the terminal device receives an uplink grant, when performing resource allocation based on the uplink grant (for example, performing LCP process), the MAC entity of the terminal device performs uplink grant allocation based on the uplink resource allocation rule information configured in step a2.
In this step, for a path (for example, a logical channel) in the activated state, the MAC entity may perform the uplink grant allocation by using the first uplink resource allocation rule; and for a path (for example, a logical channel) in the deactivated state, the MAC entity may perform the uplink grant allocation by using the second uplink resource allocation rule.
For example, if the uplink grant is an uplink grant for the path (for example, a logical channel) that is available, the path is included when the MAC entity performs uplink grant allocation (for example, performing LCP process). If the uplink grant is an uplink grant for the path that is unavailable, the logical channel is not included when the MAC entity performs uplink grant allocation.
Example 2: Paths of One Bearer Correspond to Different MAC Entities, as Shown in FIG. 4Specifically, the resource allocation method in this embodiment of this disclosure may include the following steps:
Step b1. The network-side device configures a plurality of available paths for transmission or reception for a bearer of a terminal device.
For example, as shown in
Step b2. The network-side device configures uplink resource allocation rule information for one or at least two paths of the bearer of the terminal device.
It should be noted that, reference may be made to the foregoing description for the uplink resource allocation rule information. Details are not described herein again.
It should be noted that configuration information of the step b1 and step b2 may be transmitted through one or different pieces of signaling, which is not limited in this embodiment of this disclosure.
Step b3. After the terminal device receives an uplink grant, when performing resource allocation based on the uplink grant (for example, performing LCP process), the MCG MAC entity or the SCG MAC entity of the terminal device performs uplink grant allocation based on the uplink resource allocation rule information configured in step b2.
In this step, for a path (for example, a logical channel) in the activated state, the MCG MAC entity or the SCG MAC entity may perform the uplink grant allocation by using the first uplink resource allocation rule; and for a path (for example, a logical channel) in the deactivated state, the MCG MAC entity or the SCG MAC entity may perform the uplink grant allocation by using the second uplink resource allocation rule.
For example, if the uplink grant is an uplink grant for the path (for example, a logical channel) that is available, the path is included when the MCG MAC entity or the SCG MAC entity performs uplink grant allocation (for example, performing LCP process). If the uplink grant is an uplink grant for the path that is unavailable, the logical channel is not included when the MCG MAC entity or the SCG MAC entity performs uplink grant allocation.
It should be noted that when performing uplink grant allocation, the MCG MAC entity or the SCG MAC entity of the terminal device only allocates the uplink grant to its corresponding path(s). For example, as shown in
